PIPE

Filed April 6, 1955 INVENTOR Su.vxo GUIDA 8&&WW ATTORNEY Pafented Sept.24, 1935 UNITED STATES PATENT OFFICE PIPE Silvio Guida, Hudson Heghts,N. J. Application April 6, 1935, Serial No. 15,072 6 Claims. (Cl.131-12) This invention re1ates to new and. useful improvements in a coolmoistless pipe.

The invention has for an object the construction of a pipe as mentionedwhich is characterized by an aluminum coupling element arranged betweena, pipe mouth piece end a pipe stem, and said coupling element beingassociated With an aluminum tubular element supportng a hygiene glasstube having a. closed end in a. particular manner so that saliva,entering the pipe may be collected end prevented from reaching the bowland the heat of the smoke reduced by the aluminum a.nd glass members.

Still further it is proposed to so arrange the parte that moisture drawnup from the tobacco Will dscharge into the glass tube With the closedend instead of being drawn into the smokers mouth and the glass tubewashed or emptied. at Wll.

A still further object of the nvention s to construct the aluminumtubular member so that it is formed-with a longitudinal slot, and toform the glass tube With the closed end with an opening alignable wththe slot in a manner so as to produce the objects mentioned.

Furthermore, the invention contemplates an arrangement whereby theslotted. tubula.r element may be adjusted so that the slots thereofcoact with difierent openings formed in the tube With the closed end.

Another object of the invention is the construction of a device esdescribed which is simple and. durable and which can be manufactured andsold at a. reasonable cost.

For further comprehension of the invention, and of the objects endadvantages thereof, reference Will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel fea.tures of the invention are more particularly setforth.

In the accompanying drawing forming a ma.- terial part of thisdisclosure:-

Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 s a perspective view of the coupling element end tubular member,illustrated per se.

Fig. 4 is a perspective view of the tube With the closed endillustrated. per se.

Fig. 5 is a fragmentary longitudinal sectional view of a pipeconstructed. according to another embodiment of the invention.

Fig. 6 is a. perspective view of the coupling element end tubularelement used in the device shown in Fig. 5.

The pipe, according to this invention, comprises a pipe bowl Il] havinga. pipe stem Il associated. With a mouthpiece 12. A coupling e1e- 5 ment|3 is arranged between the pipe stem end. mouthpiece for joining theseparts separably together. This coupling element 13 is made of aluminumend supports a tubular element 14 of aluminum extending to the base ofthe stem and formed With a longitudinal slot |5 having its bottom end l5communicating Wth the bowl IO. A glass tube |6 is non-rotatvely andtightly mounted through the coupling element I 3 and into said tubularelement l4 and has a. closed bottom 15 end adjacent the bowl and isformed With an opening- I"! intermediate of its ends and communicatingWith the top of the longitudinal slot l'5. This construction reduces theheat of the inhaled smoke, since the aluminum coupling I 3 is surroundedby atmospheric temperature end both the aluminum coupling 13 and thealuminum tube I4 are good conductors of heat.

More particularly, the pipe bowl Il), the stem II, and the mouthpiece I2are of standard construction and design. The device difiers from priordevices in the arrangement of the coupling |3, the tubular element Iand. the glass tube 16. More specifically, the coupling I 3 comprises a.central enlarged portion |3 by Which it may be operated, and threadedends I3 end. |3.

The threaded end l3 threadedly engages into the adjacent end. of themouthpiece I 2. The threaded. end |3 threadedly engages into the stem lI. A small tube I8 engages partially within the passage of themouthpiece I 2 end. partially extends into the open end of the tube l6.This tube l8 should be preferably of whte metal but it may be of anyother suitable material.

The tubular element [4 is ntegral with the threaded end l3 of thecoupling end extends into the base of the stem II. The longitudirialslot |5 extends from the base end of the tubular element to immediatelyadjacent the threaded portion I3. The tube |6 is held against rotationrelative to the coupling |3 by reason of small projections !9 from thesides thereof engaging into receiving recesses 20 upon the free end ofthe threaded portion l3. This interengagement of parts is such as tohold the tube 16 in a. position in whch the opening I! aligns with thelongitudinal slot I5.

In Figs. 5 and 6 a modified form of the invention has been disclosedwhich is very similar to the previous form, similar parts beingindicated by identical reference numerals, bui; distinguishing in thefact that the tubular element is rotatively adjustable relative to thecoupling Within a limited scope so that longtudinal slots therein maya1ign With openings in the tube IB. More particularly, there is atubular element l4 having its upper end rotatively engaging within thematerial of the coupling l3, and extending into the base of the stem andformed with diametricaily opposite, or at other angular distances,iongitudinal s1ots I5 and 15".

A pin 2! projeets from the tubular element M and operates in a,transverse slot 23 formed in the material of the coupling !\3. Thearrangement is such that the end of the pin 2| projects so that thetubular element M may be turned as limited by the ends of the slot 23.The tubula'r element M maintains adjusted positions trictionally.

The tube i5 is formed With several operiirigs' l3 and 13 arranged sothat one or the other opening aligns with one or the other of thelongitudinal slots |5, 'I", depending upon the adjustment of therotative position of the tubular element M.

The operation of the device may be understood from the foliowingdescriptonz-Whem the pipe is being used and the smoker draws in, thesmoke Wi11 pass through the longitudinal slot I5, through the opening i,and through the mouthpiece of the pipe. The moisture Wil1 run downhillso to speak, and collect in the closed end of the tube H5. It will bequite difticult to draw the moisture up into the mouth of the smokersince air will be drawn in through the bow1 instead. Saliva from themouth of the smoker instead of reaching the tobacco in the boWl willalso be collected in the tube H5. The tube may be cleaned after eachsmoke or whenever desired. It is readily removable merely by removingthe mouthpiece 12 and then lifting the tube from ts position.

In the form shown in Fig; 5 there is an airangement whereby the passageof the air may be contrciied. For exampie, shou1d a small piece oftobacco eleg the passag"e 55, the smoker need only move the pin 2! so asto turn the tubular mernber 1% to connect the passage !5 With theopening H". Thus, the smoke may be completed without necessitating theseparation and. cleaning of the pipe.

The passags [5, or 15 af1d lfi'may be readily cleaned by removing thecoi1pling [3 from the end of the pipe stem. While I have illustrated anddescribed the preferred embodiment of my invention, it is to beunderstood that I do not limit myself to the precise construction hereindisclosed and. the iight is reserved to all changes and modificationscoming Within the scope of the invention as defined. in the appendedclaims.
